I don't have a clone recipe for skull splitter but it's a wee heavy. I do my wee heavy with mostly MO with just enough roasted barley to get you into the color range you're looking for.

I pull off a gallon of the first runnings, boil it down to thick syrup, and add it back to the kettle.

For hops I go with EKG at 60 for bittering and some at 20 minutes as well.

Ferment with 1728 or equivalent at 60F.

For mash temp/time I'm not sure. For my recipe I go low and long (148F for 2 hours), but I'm shooting for an OG in the 1.120 - 1.130 range. I'm planning on doing a "light" version sometime this year that will be in the 8% ABV range and I'm still deciding how I want to approach it.

That sounds very close to what I'm planning for what will be my very first Wee Heavy. Mostly Crisp Marris Otter plus two ounces of Roast Barley. Also thinking of adding 8 ounces of Honey Malt (cuz I have it and I like it). Brewed an Irish Red with 1728 last weekend so that'll be my starter for the Wee Heavy weekend after next. Also planning on doing the "boil down a gallon of first runnings" thing. Shooting for 1.100.

Most of the good wee heavies seem to follow the Traquair clone route, which is a good thing. 99% base malt (Golden Promise preferably, or Marris Otter), and 1% Roast Barley, then kettle caramelize the hell out of 1 gal of 1st runnings. Bittering hops only (EK Goldings, Fuggles or N Brewer) to style.

And for what it's worth, Skull Splitter is just one of Orkney Brewing's fine offerings. Try Red MacGregor, or Dark Island.
